            Bug ID: 103282
           Summary: XWayland refresh rate locked to 60 Hz
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: XWayland
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: grmat at sub.red
        QA Contact: xorg-team at lists.x.org

Looks like xwayland doesn't report the correct refresh rate/vsync timings(?) to
clients. I've been working around compositor implementation flaws by using a
custom EDID file. Now the compositors I've tried (Mutter, KWin, Sway) run at
the correct 144 Hz, however xwayland clients still only refresh at 60 Hz.

This is bad because if using a monitor with no even multiple of 60 Hz (like 72,
75, or 144 Hz monitors), there is stutter instead of smooth playback. And I
guess many common apps will be running through xwayland for quite some time.

I can also confirm the problem running glxgears, which runs v-synced and prints
60 FPS to the console.
